Two draft genomes of fungal leaf endophytes from tropical gymnosperms.

Two ascomycetes, sp. and sp. were isolated from healthy leaves of the tropical gymnosperms (Z2) and (Z50) from Panama.

Leaf Endophytes Relationship with Host Metabolome Expression in Tropical Gymnosperms.

Plant-microbe interactions play a pivotal role in shaping host fitness, especially concerning chemical defense mechanisms. In cycads, establishing direct correlations between specific endophytic microbes and the synthesis of highly toxic defensive phytochemicals has been challenging. Our research delves into the intricate relationship between plant-microbe associations and the variation of secondary metabolite production in two closely related Zamia species that grow in distinct habitats; terrestrial and epiphytic.

Antagonistic effects of native strains of the soil fungus against gastrointestinal nematode and protozoan parasites of pigs in Panama.

A variety of gastrointestinal parasites naturally infect domestic pigs in Panama which may also occur as zoonotic infections in humans. Anthelmintic drug treatment, including mass drug administration, can lead to drug resistance, reflecting a need for alternatives. The objectives of this exploratory and observational study were: (1) to isolate and cultivate natives species of from natural soils in Panama, and (2) to evaluate isolated strains for their capacity to parasitize endemic gastrointestinal nematode and protozoan parasites recovered from naturally infected domestic pigs by observing cultures for spore adhesion and hyphae penetration phases.

Antibacterial Activity of Volatile Organic Compounds Produced by the Octocoral-Associated Bacteria sp. BO53 and sp. GA327.

The present research aimed to evaluate the antibacterial activity of volatile organic compounds (VOCs) produced by octocoral-associated bacteria sp. BO53 and sp. GA327.

The patchiness of epifoliar fungi in tropical forests: host range, host abundance, and environment.

Fungal symbioses affect the diversity, dynamics, and spatial patterns of trees in tropical forests. Their ecological importance is partly driven by their inherent patchiness. We used epifoliar fungi, a guild of common, benign, obligate, fungal symbionts of plants, as a model system to evaluate the relative importance of host phylogeny, host relative abundance, and microclimate on the three-dimensional distribution of plant-fungus symbioses.
